Platinum Carbon Black Ink

This is one of my favorite everyday black inks. It’s permanent — incredibly water resistant and lightfast — while also being just a wonderfully performing ink. It dries quickly, flows well, and has a nice dark color with the tiniest bit of sheen.

A word of warning: don’t load this ink into hard-to-clean pens or clear demonstrators (it can stain). Handle carefully. Enjoy.
